Product Description:
The CHINT NXMLE-160S/4300 160A MCCB is a premium 3-pole molded case circuit breaker with built-in earth leakage protection, engineered for high-demand three-phase systems. Rated at 160A, it integrates thermal, magnetic, and residual current protection in one device—eliminating the need for separate MCCB and RCD units.

This model supports adjustable leakage sensitivities of 100mA, 200mA, and 300mA, giving you precise control over fault detection. With a strong breaking capacity of 50kA at 230V / 36kA at 400V, it is ideal for power distribution panels, critical loads, and environments where electrical safety is non-negotiable.
